Application filed January 14, 1927. Serial No. 161,083.

This invention pertains to ring twisting or spinning frames employed in the textile industry for the preparation of yarns and threads andrelates more particularly to means for automatically lubricating the rings and travelers of such a frame.

Various arrangements have heretofore been proposed for lubricating the ring and traveler, most of which either necessitate the use of rings of special and ofttimes expensive construction or provide so inadequate a supply of lubricant that they must be given almost constant attention.

Qt recent years the tendency has been to increase the speed of the twisting or spinning spindle and the high speeds now em-= ployed make the problem of lubrication of the ring and traveler very important. Tn accordance with the present invention, ll so effectively lubricate the ring and its traveler that an increase of as much as above the normal spindle speed is obtainable without appreciably increasing the temperature of the ring and traveler and l obtain this result without discarding the rings of ordinary type, with which existing machines may be provided, since it requires but slight expense to adapt such rings for the purpose oil the present invention.

Moreover, in accordance with my inven= tion the attendance cost, for insuring proper lubrication, is reduced to a n'iinimum.

. Tn the accompanying drawings 1 have il lustrated a preferred embodiment of the present invention and in the drawings,

, Fig. l is a fragmentary plan view or one end of a ring rail having the present invention incorporated therein;

Fig. 2 is a verticalsection substantially on the line 22 of Fig; it; and

Fig. 3 is a fragmentary plan view illus= trating a slight modification.

The present invention may be considered to constitute an improvement over the arrangement disclosed in the expired patent to Carter No. 355,506, January it, 1887. In the patented device the attempt was made to provide lubrication for the traveler and ring without substantially modifying the ring but in accordance with this patented arran ement the reservoir for the oil is oil such imited capacity that almost constant care on the part oi" the attendant is necessary to insure proper lubrication, Furthermore, the wick a, which in the Carter device con stitutes the reservoir, is exposed atthe front face of the ring rail so that the lubricant tends to flow outwardly along the front edge of the rail to the same extent that it tends to flow inwardly toward the interior of the ring and thus substantially one-half of the oil supplied is wasted, Moreover, this waste oil flowing over the front face of the rail produces an accumulation of lint and dust which must frequently be removed lln accordance with the present invention it provide a reservoir of large capacity and having but a single outlet so that all oil the oil is usefully employed.

Referring to the drawings, the numeral 1 designates the ring rail which may be ol any usual type and this rail is provided with a plurality of spaced openings of which one only is illustrated, this opening being designated by the numeral 2. These open= ings in the ring rail are adapted to receive the twisting or spinning rings, such a ring 3 being here shown as seated in the opening 2 and removably secured in position by means of the usual set screw 3. The ring it carries the traveler l which may be of usual construction and which is adapted to re volve about the ring under the action of the thread. While it have shown but a single traveler on the ring, T may, it? desired, and as is common for certain purposes, provide a plurality of such travelers, this forming no part of the present invention.

In accordance with the present invention ll provide a chamber 5 of large capacity as compared with prior constructions of lilre purpose. This chamber extends downwardly from the upper surface of the rail into: the substance of the latter to a suitable depth, and is conveniently formed by drilling a hole downwardly into the rail, using a drill of the proper diameter as here illus trated ofthe order of one half inch, but stopping the operation before. the drill breaks through the under surface of the rail, I now provide a passage 6 extending from the opening 2 laterally through the substance of the rail into the chamber 5. This passage may conveniently be formed by drilling from the wall of the'opening 2 outwardly and this passage is of relatively small diameter as compared with the di 11i eter of the chamber 5. The ring 3 may be an ordinary ring of usual type and to adapt this ring for use in accordance with the present invention, I

merely drill achannel or passage 7, prefer ill) all

lit

till

ably radially, through the thickness of the ring", and in setting the ring in the rail 1' cause this passage or channel 7 to register with the passage 6, the diameter of the passages 6 and 7 preferably being substantially alike.

l now arrange a mass of oil-absorbent material 8 within the chamber and preferably extend a portion of this oil-absorbent material inwardly through passages 6 and 7, as shown at 9 terminating the inner end of this absorbent material substantially flush, as shown at 10 with the inner surface of the ring 3. However, the end 10 is so close to the path ot' the traveler 4: as the latter moves about the circumference of the ring, that oil in minute amounts is transferred to the surface of the traveler each time the latter passes the end ll) of the absorbent material.

l reterably ll arrange this absorbent material in the term of a wicln for example, a piece of soft slubbinpg roving or woolen yarn having a diameter substantially like that ol the passage ti and having its main part coiled or otherwise disposed within the chamber 5.

lll 'hile l have shown the passages 6 and 7 as substantially horizontal and radial with respect to the ring 34, l contemplate that there passages may be inclined either up-- wardly or downwardly or it desbsed. may extend in a direction which is not in a radial plane ot the rinn; Eli, ll :t'urtill their eontemplate that while the chamber may: as a re rltaaaribed he termed vealently by the use, at a drill and thus it e a clrnalar no l nay termed in a liar ways and be taper in anymanner ele sired.

The chamber 5 may be supplied with oil which is absorbed by the wick 8 and which moves along the latter by capillary" attrae tion laseieted by gravity so that the inner end of the wiclr is constantly moistened with lubricant and turnishea a very small quan tity at lnbrieant to the traveler at each pate the latter across the re ardant the wieln the chamber 5 no otheroutlet than the a esta e a it iinnoaaible tor the lnbri-- narrate cant to'escape at undersired points so that all of the lubricant is usefully employed and is not wasted upon'the outer surface of the machine. The chamber 5,as above stated, is of large capacity as compared with the diameter of the passage 6 so that it may furnish lubricant for a relatively lonp period of use; thus the attendant may supply oil to the machine at the beginning of the days work and the oil supply thus furnished may be depended upon to last through the day and even longer, provided the chamber 5 be of the relative size here illustrated, or larger.

ln the arrangement shown in Fig. 3, the rail l has the chamber 5 as in the arrangement previously described, but this chamber.

has two passages t3 and ti leading to the inner surl'ace of ring, and the wick 8 is so arranged that its opposite ends are disposed within the respective passages 6 and 6,

ll claim:

A ring rail having a ring receiving opening, a ring of substantially usual type seated in the opening, and a traveler mounted on the ring, the rail having an oil receiving chamber adapted to receive a substantial coil of wiclr material and ext-ending downwardly into its substance from its upper face at a' point intermediate the ring receiving opening and the trout edge of the rail, the wall ot the chamber being impertorat-e at the side opposite to the ring, said chamber havan outlet passage extending horizontally from its lower part to the ring; receiving opening, the ring having a passage aligned with the passao'e in the ailand extending to the inner :nir' ace out the in chamber in the rail below th passapge in the rail and being ot a capaeity suttlcient to hold oil tor lubricating; the ring and traveler throughout at least one dott or change of bobbins, and an oilabsorbent wick having a relativelylarge portion disposed in said chamber and a relatively small portion extending through the aligned passages in the rail and rin p; to the inner eurtaee at the ring day at vlannary rear, b
